WILLIS Roscoe-BENSON. OF OAKLEYQIDA i To all whom it may concern;

Be it known thatI, WiLLis Ro'soonV BEN- fsoN, of Oakley, county of Cassia, State of Idaho, have invented a new and useful Sheep-Shearing Machine, to be known asl the Benson sheep-shearing machine, and that a power supplying source and by an indi-V the same,

' Fig. 11 shows the gearbearing cup.

the same has not been patented in anyl country. v

The nature purpose of shearing the woolV from sheep. It will be operated by attaching the same to vidual guiding and controlling the machine. l In the drawings, 1

Figure l is an elevational' view of the in' ,vention,

thefollowing detailed explanation' is given.

The machine is to bejconstructed' ofV steel with the exception of the covering.` of the hull which will be'constructedfof aluminum, which covering is designated by the letter E in all three figures on Sheet I of the drawings. The base of the machine consists of a steel plate circular in shape with .13 teeth or projections extending from one side a little over an inch, the upper sideof which projections are gro-und to a, sharp edge. This plate A'is called the comb and isifastened to the aluminum covering l E above mentioned by means of screws L.

Above this comb A and made to revolve on the same is the cutter B, which cutter consists of a rim of steel yin the form of aV circle, on the outside of which appear twenty y curved projections pointing in a uniform direction, and ground to a sharp edge.v This 'cutter B is Afastened by Ameans of three i v, if-Sgm Specification of Lettersrjfatentnz.
